5. Always check the connections before wiring to prevent fire.

6. Use the sensor within its rated specifications to avoid fire or product damage.

7. Clean the sensor with a dry cloth and avoid using water or organic solvent to clean it as it may result in fire.

8. When installing the sensor, follow the recommended tilt angle for through-beam, retroreflective and reflective sensing types.

9. For sensor-reflector installations, ensure that they are at least 0.1m apart and parallel with the sensing side of the unit.
   For BGS reflective types, recommend horizontal/back and forth movements of sensing target.

10. When selecting a specified model, follow the Autonics website as the actual product does not support all combinations.

11. Refer to the operation timing chart for Light ON mode and Dark ON mode.

Cautions during Use

• Follow instructions in ‘Cautions during Use’. Otherwise, It may cause unexpected accidents.

• When connecting an inductive load such as DC relay or solenoid valve to the output, remove surge by using diodes or varistors.

• Use the product after 0.5 sec of the power input.
  When using a separate power supply for the sensor and load, supply power to the sensor first.

• 12-24 VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.

• Wire as short as possible and keep it away from high voltage lines or power lines to prevent surge and inductive noise.

• When using the switching mode power supply (SMPS), ground the F.G. terminal and connect a condenser between 0V and F.G. terminal to remove noise.

• When using a sensor with noise-generating equipment (e.g., switching regulator, inverter, and servo motor), ground F.G. terminal of the equipment.

• This unit may be used in the following environments.

  • Indoors (in the environment condition rated in ‘Specifications’)
  • Altitude max. 2,000 m
  • Pollution degree 3

Cautions during Installation

• Be sure to install this product by following the usage environment, location, and specified ratings. Consider the listed conditions below.
  • Installation environment and background (reflected light)
  • Sensing distance and sensing target
  • Direction of target’s movement
  • Feature data
• When installing multiple sensors closely, it may result in malfunction due to mutual interference.
• BGS reflective : If the sensing target has a glossy surface or high reflection, tilt the sensor with an angle from 5 to 10 degrees and install it. Get rid of the effect of background object on the sensing performance.
• Narrow beam reflective: Mount the sensor tilted at an angle from 0 to 15 degrees for stable copper wire detection.
• For installation, tighten the screw with a torque of 0.5 N m. Mount the brackets correctly to prevent the twisting of the sensor’s optical axis.
• Do not impact with a hard object or bend the cable excessively. That could decrease the product’s water resistance.
• Use this product after the test. Check whether the indicator works appropriately for the positions of the detectable object.

Circuit

• OCP (over current protection), SCP (short circuit protection)
• If short-circuit the control output terminal or supply current over the rated specification, normal control signal is not output due to the protection circuit.

Sensitivity Adjustment

• Set the adjuster for stable Light ON area, minimizing the effect of the installation environment.
• Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent product damage.
• The steps below are based on Light ON mode.
